Cross-site request forgery (CSRF) vulnerability in TWiki before 4.3.2 allows remote attackers to hijack the authentication of arbitrary users for requests that update pages, as demonstrated by a URL for a save script in the ACTION attribute of a FORM element, in conjunction with a call to the submit method in the onload attribute of a BODY element.
